Aw smokes, I did a search, why did I not see this before I posted?
Sorry for the dupe. Mouser, you can erase mine, it doesn't add anything but the misleading tagline, and I totally missed the fact that it was the extension that had the bug, not VS.
Still, it seem somebody at MS or GitHub should have caught this bug long ago. Is it that uncommon to make private repos on GitHub?
